The number of eighty fours in 672 is 8

  • How many eighty fours are in 672
  • Let x represent the number of the 84 (can be expressed as 84 x X)
<h2>Further Explanation</h2>

And since we have 672 as the total value,

Therefore, you have:

84 x X = 672

84x = 672 (then determine the value of x)

X= \frac{672}{84}

X = 8

Thus, the number of eighty fours in 672 is 8.

Prove:

= 84 x 8

= 672

Notably, eighty fours is expressed as 84

<u>You can also solve this question easily by following this step: </u>

It is same as saying how many 84’s are in 672 (it means you should divide 672 and 84)

= \frac{672}{84}

= 8

<h3>Check out these 2 examples: </h3><h3><u>Example 1</u></h3>

How many eighty fours are in 4200 (same as how many 84’s are in 4200)

= \frac{4200}{84}

= 50

Prove:

= 84 x 50

= 4200

<h3><u>Example 2</u></h3>

How many eighty fours are in 840 (same as how many 84’s are in 840)

= \frac{840}{84}

= 10

Which of the following is a factor of 64x^3 +343
Lyrx [107]

Answer:

(4x + 7) or

(16x^2 - 28x + 49)

Step-by-step explanation:

This is the sum of cubes. If you have choices you really should list them because often the way  we write  answers is not in agreement with what you are given.

Step One

Factor 64x^3  and 343 into prime factors.

64x^3: 4*4*4*x * x *x

343: 7 * 7 * 7

Step Two

Factor using the sum of cubes.

(4x + 7)([4x]^2 - 7*4x + 7^2)

(4x + 7)(16x^2 - 28x + 49)
